To all whom it may concern:

-Be it known that l, CLAUDE It. SWAIM, a citizen of the United States,residing at Muncie, inthecounty of Delaware and State of Indiana, haveinvented certain new and useful improvements in Door-Holder Devices, ofwhich the following is a specification. I

This invention relates to improvements in "door-holdingdevices. That isto say,-devices for holding or retaining the door against movementfrom'a fixed location'in its open position.

The object of this invention is to provide a device capable of beingeasily applied to doors of business bui dings or dwellings, and/by theuse of which the door may be easily fastened at any'desired point orlocation in its swing from the closed to the entirely open position, andwhereby it may be easily released I .I am awnre that, devices having thesame general purposes as above stated have heretofore been made.Accordingly, the more specific purposes ofthis invention are to providea device of this character which will be simple and economical ofconstruction, durable, and not liable to get out of order or repair; andwhich may be easily installed.

My improved door holder device consists of the ncw construction,combination and arrangement of parts shown, in the annexed drawings anddescribed in this specificaiion; and the invention is defined in theappended claim. K

Important] features of utility of my 1rnproved' door holder are, that itoccupies small space, that a minimum amount of plied'totheseveral partsof the device in t work is required for its installation, and that thedevice isyentirely contained and concealed within the mortise thereforin the door structure. in, the present illustration of my invention thesame is shown installed at the lower portion of the frontal edgeof anordinary wooden door of usual thicls ness. I

My invention comprises a frame case of compact form and structure havinga vertical face plate and vertical parallel sides; between these sidesis slidingly disposed an angular detent lug having a threaded hole inits bottom and to which detent lug is hingedly connected a lift handlethat normally hangs vertically in a slot provided therefor in the faceplate. A spring operable at the face plate so that when pressed inwardlythe detent head is released; a tubular guide member adapted to beinserted to secure position in the bottom of the door, a plunger in saidguide memher having a stem adapted to be screwed into the said detentlug, and a spring between the upper end .of the tubular member and theplunger, to normally depress the said plunger. By my invention as aboveoutlined, comparatively slight cutting away of the door body isnecessitated, and by merely the variation of the length of the plungerstem the device is rendered capabio of being operated at any desiredheight on the door.

In preparation for the installing of the invention, a mortise cavity Aof the shape shown in Fig. 2 is chiseled in the door. From the bottomedge of the door is then bored a hole B of the suitable diameter shown,and from this hole is extended a bore C of smaller diameter and whichopens into the cavity A.

The case or frame in which the actuating parts of my device are retainedis made of thin sheet metal, the walls 1 of which case are soldered orbrazed to the face plate 2. The transverse plate 3 constitutes a guideway for the lower end of the lift handle 4 and the side armsficonstitute guides for the pawl 6. To. these said operative partsfurther reference will presently be made. Disposed slidinglv between theside plates 1 and l and having on its sides the studs T which areadapted to have movement slidingly in the guideways h. is a detent lugT. This detent lH-g has a lieveled no e T" at its rear side. On atransverse pin in its l'r ntal portion is pivotallv connected a lifthandle 4 of the form shown in Fig. I). This li'l't handle 4 has thecurved underside and is slidinglv disposed between the plates 1 and land its lower edge -l has hearing against the transverse plate 3. .\tthe upper end of the lift handle is provided a tooth l whose function isto engage the recess T of .the detent lug T -when the lift handle isswung or pulled up to the dotted line position shown in Fig. 5.

Disposed vertically in the door structure is the plunger membercomprising a head and stem and the detent lug T hcreinhefore referredto. In the bore of a cylindrical sheet metal shell 10 that is seatedfirmly in the hole B. is the metal plunger head ll. The bottom of thisplunger head consists of a toe 11 made pret'erablv of rubber or tiher.The upper part oi this plunger member comprises a stem l2. its lower endbeing secured to the plunger head. This stem is passed through the topof the shell 10 and its threaded upper end is adapted to be screwed intoa threaded hole in the detent lug T. The opening T of the hole in thedetent lug is so llared that when the stem 1; is inserted thereat itsthreading entrancev into the hole is facilitated. t\ coil spring 13between the plunger head and the underside of the top of the shell 10urges the plunger normally to the downward position.

The pawl memlier comprises the parts as follows: The vertically arrangedpawl (3 has the tooth and the heveled face (3''. .\n arm 15 whichprojects forwardly from this pawl rests slidingly in a hole providedtherefor in the cross lHll Il. push head 16 formed on the end of the arm13 rests Slidingly in a suitable bore therel'or in the face plate 2ot'the case. coil spring lT between the push head lttand the cross bar 4acts-to urge the pawl (3 to forward position the tooth ti coming intoengagement underneath the nose of the detent lug T. ln the face plate 2is provided a slot it) of width to permit of the free movement thereinol' the lift handle 4'. The purpose of the enlarged opening 20 is topermit of the tree insertion of a person's linger to position underneaththe lo'wer end of the lift handle 4. The lower end of this hit handlehas a depression l which renders easy the engagement thereof by thefinger.

From the foregoing description. the constrnction. combination andarrangement of the several parts ma he clearlyunderstood. The inventionin readiness to install comprises the ease and its connected parts. andthe shell 10, plunger 1.1 and its stem 12.

The cavity hole B and bore t. having been prepared. the case is tirstset in position as shown in Fig. 1. By insertion of screws 2; throughthe face plate. 2 the case is held securely at place. Then the shell Wis disposed at place in the hole l) and is retained l the engagement ofthe crimped rim Hf elosel v engaging the edge of the hole B. The plungerstem 1;! passed up through the top ot shell l0 and through the bore C isscrewed into the detent lug T. The action of the coil spring 12) inurging the plunger head downwardly holds the detent lug at tightengagement with the tooth (3 of the pawl If. The installation is nowcomplet and the device is in readiness for operating. As will heobserved, the parts constituting my invention take up small space andare simply constructed and arranged. The device being entircl containedinside the door structure there are no projecting parts.

l'ntil there may he a necessity to retain the door at liXed location inits open position, the several parts of my improved door holder occupythe relative positions as shown in l*'igs. l, 2 and the plunger 11 beingretained at retracted position by the engagement of the nose of thedetent lug T with the tooth G of the pawl (3. The door being swung opento the location desired, a slight pressure by the finger against thepush head lti causes the tooth G to be disengaged from the detent lug.The spring 13 being then unresisted, its instant action causesn-downward movement of the plunger head 11 the toe l1 thereol' makingcontact with the floor surface. The relative positions then of theseveral parts are as shown in Figs. 4 and 5.

To retract the plunger from the lowered position and thereby to releasethe door from its position held as described, the finger is applied atthe opening 20 and at engagement with the depression 4" of the lifthandle 4 and thence as the lift handle is swung outwardly and upwardlyto the dotted line position as shown in Fig. 5, to the rounded portion1". With the lift handle at the horizontal position, the tooth 4 restsin engagement with the recess 7 so that upward movement of the lifthandle causes. in turn, an upward travel of the detent lug and itsconnected parts. By an upward pull or hit then exerted upon the lifthandle. the face T of the detent lug passes the face t' of the pawl 16,and simultaneously with the snap return of the pawl to position shown inFig. 3. the detent lug T will have again been engaged, and the plungerhead it will have been returnedto the normally raised position. Theusers hold on the lift handle being then released, the) lift handleswings by its own weight, back to the. normal vertical position asshown.

This invention besides having the advan- 'ture to allied lines ofhardware for doors,

such as lock and bolt devices, the correct method of preparing themortise openmgs and of placing the parts in position and connectingsame, is-capable of being readily understood and practised by a mechanicof ordinar ability.

There the further advantage. of the ease I of manipulation or use ofsame, it being obvious to any person that to exert a pressure on thepush head 16 will cause action of the device, and again, it being quiteas apparent that to cause a return 0 the plunger to the-raised position,there would be the use of the lift handle.

In this specification I have shown the form of embodiment deemedpreferable. I ani aware-that minor changes may be made in theformandconstruction of the details of construction without departingfrom the nature or spirit of the invention as defined by the appendedclaim, or of sacrificing any of its advantages.

What I claim as my invention, and desire to secure by Letters Patent, is

A door holder device,-comprising a frame adapted to be seated in amortise provided therefor in the door, the face plate of said framehaving a vertical slot, a detent lug disposed slidinglybetween the sidesof said frame and having a threaded hole in its bottom side, and therebeing transverse studs on said detent lug to move in vertical guidewaysin said frame, a tubular guide member adapted to be inserted to secureposition in the bottom of the door, a plunger slidingly disposed in saidtubular guide member and having an upwardly disposed stem adapted to bescrewed into the said detent lug, a spring in said guide'member tonormally depress the said plunger, a spring pressed pawl retainedslidingly between the sides of said frame to engage and hold the detentlug at the raised position but which pawl is adapted tobe shifted fromsaid engaged position, and a lift handle loosely connected to the saiddetent lug and arranged to normally hang in the slot of said face platebut which when swung outwardly has fixed engagement with the detent lug.

In testimony whereof I affix my signature in the presence of tWowitnesses.
